Maximally Persian people will also be held this year from August 12th to August 13th, but the observation may be partly overlooked by the month, which at that time will be a few days before full.

However, after sunset around 3 o'clock, conditions will improve.
Astronomer Juraj Tóth, vice-dean of the Faculty of Mathematics, Physics and Physics, said it for TASR
in Computer Science from Comenius University (UK) in Bratislava. "If any
continue until late at night or early in the morning,
the time before braking will be ideal for observing meteors, "
said Toth.

Constants are actually small dust particles coming from
by Comet 109P / Swift-Tuttle, discovered 1862.
Oort cloud, which is located at the boundary of the Solar System.
At ten kilometers in size, it belongs to giants in its category and theirs
orbital time is 133 years. Last time by the Sun,
and Earth, in 1992, and is expected to return
in 2126. The comet particles, mostly smaller than grains of sand, are
located along its elliptic orbit.

When the Earth in orbit around the Sun is in the area in which
it crosses the path of a comet, the particles flying into their atmosphere relatively high
at 59 kilometers per second. By doing this, they heat up to a temperature above
1600 degrees and burns rapidly at an altitude of 80 to 120 kilometers
above the earth.

It is this light phenomenon called the meteor, while the particle that has it
Causes are, according to scientific terminology, a meteoroid. If the item
does not burn in the atmosphere, but hits the surface of the earth, it is a meteorite.
And extremely bright and radiant meteors often leave smoke
the track is called bolide.

The rate of meteor rain then depends on where the Earth is located
crosses the area where the comet particles are located. Well, what
"Dense" is the particle flux at a given location.

"Peaches have a constant rate of spread that varies
between 100 and 120 meteors per hour in ideal conditions, which
it actually means that the ordinary observer can see them around
However, there are years when the frequency of meteors can be doubled,
about 200 per hour and about 100 for an ordinary observer
the exceptional frequency of Persians was last seen in 2016. This
however, this extraordinary activity is not expected for one year, "

Tóth explained.

Particles are monitored by cameras that continuously monitor the night
heaven. According to Toth, it is possible to deduce what the orbit was like from the orbits
Comet Swift-Tuttle at the time when it produced these items – that's when
the last time she went through perihelion, the area closest to the sun.

For example, observation cameras capture the action of meteor swarms
AMOS system, which was created precisely in the Astronomical and Geophysical system
Observatory (AGO) UK near Modra. "Our system is
special because it has cameras all over the world. Five cameras down
located in Slovakia, there are two in the Canary Islands, two in Chile
the Atacama Desert and two others in the Hawaiian Islands. Three cameras are coming
place in Australia and three more in Namibia, so we'll be covered
the whole world, and the south and the north, "
he said for
TASR Dušan Kalmančok from AGO-Modra.

Tóth and Kalmančok are among the authors of the AMOS system. scientific
however, visual observation is also important when experiencing watches
observers across the globe and compare observations
of every year.

The meteor shower was given the Persian name because of the radiant from which the meteors
apparently flying upward, it is precisely in the region of the constellation Perseus that in this one
time rises late in the evening over the northeast horizon. They are also called
The tears of Saint Lawrence according to the saint were burned on 10 August
258 in Rome.

According to scientists, brighter meteors will be visible despite the month
light.

A deciding factor is also light pollution – better with meteors
observe foreigners through public lighting. Weather forecast
So the Slovak Hydrometeorological Institute must be a little cloud
favorable. In addition, they are extremely clear among the Persians
bolide.

Unlike other weather shoes, which have a very short time
maximum duration, depending on the region of comet bodies
109P / Swift-Tuttle flies over Earth for quite some time. Therefore the action is Persistent
observable for a longer period – from the end of July to the end of August.
And even on clear weekend nights it's a great opportunity "go down
stars "
to observe.
